Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Chromosome‐Level Genome Assemblies of Two Softshell Turtles with ZZ/ZW Provide Insights into TE‐Driven Recombination Suppression in Sex Chromosomes

Integrative Zoology, EarlyView.
This study presents the first genomic identification and characterization of ZW sex chromosomes in two soft‐shelled turtle species through genome assembly and resequencing. We reveal the structural organization of ZW chromosomes, identifying both pseudoautosomal regions (PARs) and differentiated regions.

ESTIMATING SINGLE FACTOR JUMP DIFFUSION INTEREST RATE MODELS [PDF]

Recent empirical studies have demonstrated that behaviour of interest rate processes can be better explained if standard diffusion processes are augmented with jumps in the interest rate process.

Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider

Integrative Zoology, EarlyView.
The graphical abstract contrasts sex‐equivalent cognition (route‐planning & memory) with female‐biased nest architecture. Both sexes perform similarly in cognitive tests, but females build complex, geometry‐matching nests while males make simple shelters.

The Rasch Sampler

The Rasch sampler is an efficient algorithm to sample binary matrices with given marginal sums. It is a Markov chain Monte Carlo (MCMC) algorithm. The program can handle matrices of up to 1024 rows and 64 columns. A special option allows to sample square

Decayed MCMC filtering

, 2002
Filtering—estimating the state of a partially observable Markov process from a sequence of observations—is one of the most widely studied problems in control theory, AI, and computational statistics.
